Check your VGA cables to make sure it's properly connected (if you haven't already). If that does not work, Take the CMOS battery out of your motherboard and leave it out for a minute, then put it back in. If that still doesn't work, make another post with more specific information about your system.

power supplies are common failures..a 300Watt ATX power supply is not very expensive these days so it would be an inexpensive way to see if this is the problem..the brown spot concerns me though..seems maybe you have a filter in the supply that may have leaked electrolyte...if you have another computer with the same type of supply in it..you can try it..as long as the plugs are the same and the wattage is the same or higher
Hello Anvar, hi, to run the power supply on its own, you need to short the green wire with the black wire. (plug in the unit)
using a Volt meter, select a range of DC 50V. put the black probe of the voltmeter to any black wire, and the red probe to the ff:
Green White is for the power switch. Red-White is for the HDD LED and Black-white is for manual reset. Look at the plastic clips at the end of these wires. Generally they it written on them.......sodeep
You might try this. Shut down the computer, disconnect power cords, disconnect everything at the back of the computer, mouse, key board, etc. Open the case, ground yourself by touching an unpainted area of the case and remove the power connectors to ALL optic drives and floppy drive if you have one. (Of course do not disconnect the hdd.)
Reconnect mouse, keyboard, etc., and power cords to wall outlet.
See if it will post now. If it does I say you have a faulty power supply.
I was given a computer which was doa. It would not post, after I tried the above routine it posted then booted to windows.
I replaced the psu and now the computer works fine.
Hope this helps!
There is no specific power suppl that you need. The only differce is the wattage 300, 350 , 500 etc. Your motherboard will work with all types not to worry. The only reason you get a higher wattage power supply is if you plug in a lot of stuff. say you have 3 HDD and 2 CDROMS then you would need the 500 Watt power supply.
green-white for front panel Power indicator LED , Blue-white for RESET Switch , Orange-white for POWER BUTTON , Red-white for HDD LED . The berg pin header on the motherboard will have these legend printed just beside the connector or due to lack of space slightly away from it .
